Authors' objectives:

To evaluate selected molecular tests in diagnosis and screening of cytomegalovirus (CMV) infection in immunosuppressed patients.

Authors' recommendations: The study findings offer some evidence that a CMV screening regime is more cost-effective than diagnostic testing alone, based on the cost per true positive detected and interim outcome such as changes in patient management. However, the study was unable to demonstrate any benefits in terms of longer term patient outcomes. If CMV screening is introduced, the use of antigenaemia pp65 is clearly less cost-effective than the use of molecular tests. The study identified the optimum test for CMV screening as an in-house molecular test (single-round PCR test). This test was less costly to perform and also resulted in lower costs linked to false positives and negatives than other tests. The in-house, semiquantitative test was two to three times more costeffective than the commercial molecular tests assessed; however changes to European Union legislation may mean that it may not be feasible to use in-house tests. The use of targeted screening (limiting CMV screening to high-risk transplants) as opposed to universal screening offers a significant improvement in the cost-effectiveness ratio for haematology transplant patients, but has limited impact in the case of renal transplants. Economic analyses could be expanded tomodel the cost-effectiveness of more frequent screening tests (as reported nationally), and screening in other ‘at risk’ groups. Subgroup specific disease groups should be investigated across a larger population to allow more accurate modelling of the impact of CMV screening on disease progression. Further studies of CMV screening programmes should address a range of outcome measures, including patient outcomes.
